O ullar ndan Rüstem, bu sülalede en çok ismi geçen ki idir. Rüstem Togay Bu a,özellikle Emîr Timur un ölümünden sonra karde leriyle birlikte ahruh Mîrza n n yan nda yer alm ve Halil Sultan a kar mücadele etmi tir.

Not only hisbrother La l Barlas but also his sons Rustem, Hamza, Pir Muhammed and Ali served this state.Toghay Bugha's ancestry is based on Karacar Noyan, the same as Amir Timur. However, he knownas a prestigious amir stems from the fact that Amir Timur took his place from the beginning ratherthan being relative Amir Timur.The darugha of Bukhara was followed by his sons Rustem and Hamza. It is possible that ToghayBugha, who was a surrogate with his sons at the same times, had died before Amîr Timur. Rustem,one of his sons, is the person whose name is said to be the most. Rustem Toghay Bugha, especiallyafter the death of Amir Timur, and his brothers took place Shah Rukh Mîrza fought against KhalilSultan. Rustem, who contributed to the successful defense of Bukhara together with his brotherHamza, became one of the amir of Ulugh Beg in the later
Institution of vezirate in the Tamerlane empire and Hace Giyaseddin Pir Ahmed Hafi
No full textBu makale Timurlu Devleti"ndeki vezaretin hususiyetlerini, Hâce G yaseddin Pir Ahmed örne inde ele alarak,Timurlu Devleti içerisinde varl n gösteren vezîrlik kurumunun, Türk- slâm dünyas nda var olan vezîrlik kurumlar ndan farkl l k gösterdi ini tespit etmektedir. Klasik Türk- slâm devlet yap lanmas nda Vezaret hükümdardan sonra gelen bir mevkie sahipti. Bu temel özellik Timurlu Devleti te kilat nda görülmemekle birlikte Timurlularda vezîrlerin görevleri slâm-Türk dünyas vezareti ile birçok yönden benzerlik göstermektedirThis article examines the institution of vezirate in the Tamerlane Empire with a specific example of Hâce G yaseddin Pir Ahmed"s vezirate and shows that the vezirate institution in the Tamerlane Empire was different from the other vezirate institutions in the Turkish-Islamic world. In classical Turkish-Islamic state formation, the vezirate was the second in power after the sultan. While this feature was not present in the Tamerlane state structure, the duties of vezirs were similar to the ones in other Turkish-Islamic state

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Poly-L-lysine coated surfaces for ultrasensitive nucleic acid detection
No full textWOS: 000438025200042PubMed: 32313411Poly-L-lysine is one of the biocompatible polymers having amino and carboxyl groups in its structure. This attractive feature of poly-L-lysine makes it very convenient for bioactive molecule attachment. This study details the preparation of poly-L-lysine-based pencil graphite electrodes (PLL/PGEs) and use of the coated electrodes for direct ultrasensitive DNA hybridization detection. In the first part of this study, poly-L-lysine coated electrodes were prepared using L-lysine as the monomer by cyclic voltammetry (CV) with different cyclic scans. The effect of these cyclic scans during the electropolymerization was investigated. Coated electrodes were characterized by cyclic voltammetry, electrochemical impedance spectroscopy (EIS) and scanning electron microscopy (SEM). Then, one-pot preparation of poly-L-lysine composites with graphene (GN) and multi-walled carbon nanotubes (MWCNTs) onto the pencil graphite electrodes were achieved. Electrochemical responses of these 3 electrodes were compared. After all, electrochemical DNA hybridization was performed using the poly-L-lysine-based electrodes prepared at optimum polymerization condition. The PLL/PGE coated electrode presented a good linear response in the target concentration range of 1.0x10(-13) to 1.0x10(-6) with a detection limit of 2.25x10(-14) using differential pulse voltammetry as the detection method. We believe that poly-L-lysine-based surfaces will be useful for further clinical applications
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Boarders and day-students study together in these schools. This study was carried out to compare the quality of life of boarders and day-students the regional boarding schools. Methods: A total of 1126 students, 634 boarders and 492 day-students, at the 4th-8th grades of nine boarding schools in Giresun province of Turkey participated in this study. A socio-demographic questionnaire and a Pediatric Quality of Life Inventory were filled by the students. The Chi square test, unpaired t test, generalized linear model (GLM), and Pearson simple correlation were used for the statistical analyses. Results: It was found that the life quality scores of the boarders were lower than those of the day- students for all dimensions of the Pediatric Quality of Life inventory (p<0.05). Life quality scores of the female students were found to be lower than those of the males (p<0.05). There were positive correlations between the age and life quality scores of the boarders. Conclusions: The Life quality scores of the boarders were lower than that of the day-students. Life quality scores of the girl boarders were much lower. More attention should be given to the living conditions of the boarders in order to improve their life quality levels
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
